Description

We are using Guacamole to display a chromium browser over VNC, and after an upgrade from v1.0 to 1.3, we have found that the left 13px can sometimes be rendered outside the host browser viewport.

This happens when the host browser has a taller aspect ratio than the remote browser, and was noticed due to failing tests with a host browser at 800x600 displaying a remote browser at 1920x1080.

On further investigation, this also seems to happen consistently for the side menu when it is opened.

For now, we have worked around the issue in our tests by changing the size of the headless browser, and time permitting, may add some CSS in an extension to fix
